Cool Water Brings Improved Salmon Action to Half Moon Bay Coast

What's Biting

What's Next

The cooling water pattern documented by Captain Jared Davis of the Salty Lady is the headline development for NorCal anglers heading into the week. Western Outdoor News — Saltwater reports that temperatures below Pigeon Point dropped from 58°F to 54°F between the April 11 season opener and the current period, with NOAA buoy 46026 now showing 53°F as of May 11. That four-degree shift cleared out the bonito — a warm-water opportunist — and reset the grounds for chinook salmon. Verify current season dates and bag limits with state regulations before heading out, as salmon management zones and open periods can shift year to year.

If this cool-water pattern holds through the weekend, salmon trolling runs out of Half Moon Bay and Bodega Bay should remain productive. The 53°F range sits squarely in the sweet spot for king salmon on the central California coast. Watch for any warming trend: a return toward 56–58°F would likely push chinook back to deeper water or farther offshore, complicating the troll game considerably.

Wind conditions favor morning departures for now. Buoy 46013 is registering 5 m/s (about 10 knots) from the northwest — manageable for most sport-fishing vessels. The waning crescent moon phase means minimal ambient light at first light, historically a productive window for salmon near the surface before sun angle drives them deeper. Targeting the pre-dawn to mid-morning window gives you the best shot at surface-oriented fish. Classic NorCal afternoon northwesterly sea breezes can build to 15–20 knots by early afternoon, so morning-only offshore runs are the safer bet this time of year.

Inside San Francisco Bay, striped bass are entering their typical spring peak: mid-May is when fish transition from the Delta toward central Bay structure as water warms through the mid-50s. No fresh shop or charter intel is available for bay stripers in this report cycle, but the seasonal timing and water temperature trajectory both support growing activity — particularly on early flood tides that push bait into the shallows. Halibut are worth targeting on sandy bottom throughout the South Bay and Marin shallows as the season progresses.

Bottom line for the next 2–3 days: the cool-water regime is your friend offshore. Get out before any warming trend arrives, plan your salmon run for first light, and keep an eye on NOAA coastal forecasts for the Pt. Reyes and Bodega Bay zones before departing.

Context

Mid-May on the NorCal coast typically finds salmon season in its stride, with chinook running from the Gulf of the Farallones southward to Pigeon Point and beyond when water temperatures cooperate. The 53°F readings we're tracking this week align with a historically favorable range — central California salmon fishing tends to produce most reliably when surface temps stay in the low-to-mid 50s, keeping fish accessible for reasonable runs out of Half Moon Bay and Bodega Bay without requiring multi-day offshore commitments.

What stands out about 2026, per Western Outdoor News — Saltwater, is how warm the water was at the April 11 season opener: 58°F, which Captain Davis described as making a "huge difference on the water" relative to current conditions. That early warmth pulled in bonito — unusual early-season visitors on the NorCal coast — while suppressing the salmon bite. The subsequent cool-down to 53–54°F appears to have reset conditions much closer to seasonal norms, effectively delivering the spring salmon window later than it typically arrives but in solid form.

From a broader historical perspective, May has seen water temperatures trend persistently warmer along this coast in El Niño and post-El Niño years, which tends to push chinook activity further north or compress it into narrower thermal windows closer to the shelf break. The current 53°F reading doesn't suggest a persistent warm anomaly at this point — it looks more like a standard mid-spring upwelling correction bringing conditions back in line.

Bay Area striper fishing historically ramps up meaningfully through May and into June as the Delta run transitions toward the central Bay, but no direct comparative intel is available this cycle to gauge how the 2026 spring striper run is shaping up relative to prior years. The honest read: the offshore salmon picture, anchored by a named captain's direct observation, is the clearest signal available for this region right now. Overall, current conditions look broadly on schedule for a healthy late-spring coastal pattern.
